La proteína quinasa 2 activada por MAP quinasas (MAPKAPK2) es una enzima codificada en humanos por el gen MAPKAPK2.[1] [2]

Esta proteína pertenece a la familia de las serina/treonina quinasas. MAPKAPK2 es regulada por medio de una fosforilación directa llevada a cabo por la MAP quinasa p38. Esta quinasa, junto con p38, parece estar implicada en multitud de procesos celulares incluyendo repuestas a estrés y a inflamación, exportación nuclear, regulación de la expresión génica y proliferación celular. La proteína de choque térmico Hsp27 ha demostrado ser uno de los sustratos de MAPKAPK2 en ensayos in vivo. Se han descrito dos variantes transcripcionales del gen que codifica esta quinasa, las cuales codifican dos isoformas de la enzima.[3]
